DRINK-MIXER.

Specification of Letters Patent.

Patented Oct. 7, 1919.

Application filed March 23, 1918. Serial No. 224,119.

To all whom it may concern Be it known that I, HORACE M. SMITH, acitizen of theUnited States, residing at Chicago, county of Cook, andState of Illinois, have invented certain new and useful Improvements inDrink-Mixers, of which the following is aspecification.

My invention is mbre particularly concerned with drink mixers -which areused in connection with or attached to soda foul'l; tains wherecarbonated beverages are dispensed. It has for its object to provide adrink mixer of simplified construction drink mixer.

and mode of operation, which occupies less space than the apparatus ofthis character formerly employed, requires less attention and is lessapt to cause trouble and get out of order. v

' In the accompanying drawings I have illustrated and in the followingspecification described in detail a preferred form of It is to beunderstood, however, that the specific disclosure is for the purpose ofexemplification only and that the scope of the invention is defined inthe following claims in which I have endeavored to distinguish it fromthe prior art so far as known to me without, however, relinquishing orabandoning any portion or feature thereof.

My improved device comprises a stand adapted to be clamped or otherwisesecured to a counter or fountain and which carries a motor stationarilymounted thereon driving the mixing tool, the stand having a pivoted restplate for the glass adapted when released to swing down out of operativepositionand controlling, according toits position, the switch by whichthe motor is governed.

Inthe drawings. Figure 1 is a front elevation partly in section of apreferred form of my invention; Fig. 2 is a side elevation thereof alsopartly in section; and

Fig. 3 is a detail in vertical section on the lines 3-3 of Fig. 1looking in the direction of the arrows.

The stand is in the nature of a hollow casting 3 adapted to rest at itslower end .4. upon a flat surface and having a clasp 5 secured theretoby screws 6. The clam may be provided with the usual thum screw 7 tobear against the under side of the shelf or counter to which the deviceis attached. At its upper end the casting is offset forwardly as at 8andformed with a split casing 9 which contains the motor, of anyordinary or approved construction, the casing being provided with upperand lower bearings 10, 11 for the armature spindle 12 which projectsthrough the lower bearing and is provided with a socket 13 for themixing tool 14. The support or table 15 for the glass is pivoted on abolt or arbor 16 which is secured in lugs or posts 17, 18 rising fromthe flange 19 of the clamp. The construction of the clamp and the standis such that the glass support may be swung to the position shown infull line in Fig. 2 to sup'port the glass or drop to the position shownin dotted lines in order to permit the removal of the glass verticallydownward to clear the mixer 14 without spilling the contents of theglass. At or near one edge of the glass support but extending on theopposite side of the pivot therefrom is a heel or extension 20 having adownwardly turned end 21 to stop the upward movement of the glasssupport when it reaches the horizontal.

In order to maintain the glass support in its raised or horizontalposltion, I provide a bolt or latch 22 which is mounted forreciprocation in lugs 23,24: extendingupward from the surface of theclamp member 5. The nose 25 of the latch is beveled as shown and the,heel or extension 20 of the glass support is correspondingly beveledat26 so that when the glass support is thrown upward the heel strikingagainst the latch forces the latter. inward until the heel has clearedthe beveled nose thereof. The latch may be notched as at 27 to recivethe heel when in horizontal position.

' After the heel has passed the latch the lat- I latch by means of aplate 32 into which said latch and push'rod are threaded. 'T h e pushrod, as well as the latch, is guided in holes provided fortlie purposein the posts or standards 23, 24:. r

The switch for making and breaking the circuit to the motor is mountedupon an insulating'board or plate 33 which is sealedand protected withinthe stand and pecured to brackets 34, 35 by screws 36. For -convenientaccess to the switch the face of the stand is open opposite thereto asat 37, the opening being covered by a cover plate 38. The switch isshown as of the common knife form, the blade39 being pivoted at 40 tothe late and engaging the spring contact 41 in t e usual mannelm Theconnection for the outside wire is shown in dotted lines at 42. Theblade is provided with a bell-crank 43 which is connected by spring 44with a plate 45 mounted on the upper end of a reciprocating rod -46. Therod 46 is guided as at 47 in a lug on plate 33 and carries at its lowerend 'a head 48 which is connected by pin and slot connection 49 with alug 5O projecting from the tumbler support 15,

n arm 51 on rod 46 strikes bell crank 43 when the tumbler support '15 islowered, to force said crank past the dead center and so open theswitch.

.Preferably the glass or tumbler support is annular at 52, the openingbeing shouldered at 53 and threaded at 54 to receive a threaded disk 55.A disk 56 of rubber or the like may be interposed between disk and theshoulder .53 to form a suitable surface on which to rest the glass;

The operation of the device will now be obvious.

Normally the glass support is in the position shown in dotted lines inFig. 2 and the switch in the off .or open position. When a glass of sodaor the like "is to be stirred it is applied vertically to the stirrerand the swinging support then raised to the horizontal position shown infull lines. The latch snaps over the arm or heel 20 holding the supportin horizontal position. At the same time the switch actuating rod islowered by reason of its"described connection to the tumbler support totheposition shown in dotted lines in Fig. 1 in which, just after bladeis snapped to closed position.

the spring 44 has passed the dead center with reference to thebell-crank," the sw iltlclh e current is thus turned into the motor andthe latter continues to actuate the stirrer until intervention by theattendant. When the glass of material has been sufiiciently stirred, theattendant, taking the glass in his hand, releases the glass support bypressing the button 30,'when the support drops, at the same time raisingthe switch actuating rod so that the spring 40 passes to the other sideof the pivot of the switch, in which position it exerts a tension "toopen the switch. \Vith my improved device the stirring or mixing of adrink requires the minimum of attention and as the remoml of a glass ofliquid is impossible without at the same time turning off current fromthe motor, waste of current due to the oper- HUOH' TOf the motor when nowork is to be performed is avoided.

I claim:

1. In a device of the class described, a

stand, a motor carried by the stand, a stirrer driven by the motor, atumbler support pivoted below the stirrer to oscillate to and from thesame, a latch for'holding the tumbler support in horizontal position andmeans for operating the latch to release the tumbler support. 2. In adevice of-the class described, a stand, a motor mounted on the stand, astirrer driven by the motor, a tumbler support pivoted to the stand andhaving a rearwardly extending heel, a horizontally sliding latch adaptedto engage said heel, means normally pressing the latch into engagementwith the heel, and a push rod for releasing the latch from the heel.

3. In a device of the class described, a stand, a motor mounted on thestand, a stirrer driven by the motor, a tumbler support pivoted to thestand to oscillate toward and from the stirrer, a switch controlling themotor, a connection between the movable. element of the switch and thetumbler support for operating the former from the atter, and means forlatching thetumbler support in horizontal position.

4. In a. device of'the'class described, a stand, a. motor mounted on thestand, a stirrer driven by the motor, a pivoted tumbler support movabletoward and from the stirrer, a latch for holding the tumbler support inhorizontal position, a switch mounted within the stand and controllingthe supply of current to the motor, said switch comprising a movableblade having a bellcrank member, a vertically reciprocable' rodconnected to the tumbler support and operated thereby, the upper end ofsaid rod being adapted to pass,the pivot of'the. movable switch member,and a spring connecting the upper end of said rod with the bell-crankarm of the movable switch member.
